It is frequently desirable or necessary to mix components of a medical preparation or medicament together immediately prior to use. It is also desirable to mix components in single use batches, to assure consistency in the delivery of the combined components. Frequently, the mixing syringes or other apparatus are also used for storing and maintaining sterility of the components for extended periods prior to the time when they are to be used.
Although many mixing syringes exist, there exists a need for improvement. The present invention provides a simple, efficient multi-chamber mixing syringe device.
